How to get sender bitcoin address from transaction ID

0 votes

I am using coinpayment.net payment API for my project now.

Here is an example bitcoin transaction. https://www.blockchain.com/btc/tx/25ecdc29903aa8f80efb51a6b41ac036a91fe441aefd0d26df383827b9578cae

Here is transactionID is 25ecdc29903aa8f80efb51a6b41ac036a91fe441aefd0d26df383827b9578cae.

Sender address is bc1q3q2jw046t888slq9rrg6ypwfna7ellkxh0ytss

I want to get this sender address by programming with TxID.

If you have got any solution or API, please let me know.

I have checked coinpayments.net API, but they don't provide the sender address somehow in the webhook endpoint. So, I am trying to find out this by external API or any solution.

The purpose of this is that I want to send some BTC to the sender again every month without asking to withdraw addresses to every customer.

 You can use any scripting language with JSON support like perl, Javascipt or Python or use command line tool like jq:

curl -s https://blockchain.info/tx/25ecdc29903aa8f80efb51a6b41ac036a91fe441aefd0d26df383827b9578cae\?format\=json | jq '.inputs[0]."prev_out".addr'

to get familiar with jq use https://jqplay.org/
